In the nineteens, a rapid reduction of water pollution in the elbe River has been achieved due to limitation of emissions from major industrial sources of point pollution in the upper and middle cours (1994-1995). The non-point sources are playing
The using of discharge rate to 36 % of the long term average discharge made possible to recognize a different balance of water circulation in the river basins of CSR. The properties of the natural environment of drainage are decisive for total
frequency of the occurence of small water bearing values. (MS).
Water management problems and balance in particular river basins of South Moravia. There are 22 reservoirs in operation in general. The quality of surface water is poor. (MS).

In this paper, the existing major problems on transboundary waters in different sub-regions of Asia, such as water shortage, transboundary waters pollution, fragile eco-environment are discussed. China has 19 major international rivers and has been
faced on complicated transboundary water and eco-security issues.
The AA. examine the spatial patterns of both the average and standard deviation of water surface at an asymmetrical confluence at different flow stages. This has required the development of a new methodology to obtain reliable field data on very
small changes in water surface height. These results are interpreted with respect to visual observations of the flow structures. Simulated water surface topography from three-dimensional numerical modelling is also compared with the detailed field

Les AA. présentent les résultats de recherches sur la pollution radioactive des eaux fluviales de Biélorussie à la suite de l'accident de la centrale de Tchernobyl. Ils caractérisent la diminution totale des concentrations de radionucléides dans les
eaux fluviales au cours des premiers mois et années qui ont suivi la catastrophe, ainsi que l'état radiatif actuel actuel des eaux fluviales du bassin du Pripât. Ils présentent également une estimation comparative du rôle de l'évacuation des

The primary aim of this study has been to quantify the role of bed sediments for the water composition or water quality at the catchment scale of small flowing surface waters by means of spatial and dynamic modelling. The research areas were
An information of the occurrence, distribution and geochemical characteristics of the individual types of mineral waters in the Zvolen Basin. This basin of Middle Slovakia is rich in mineral waters among them are several evaluated as drinking table
The purpose of this paper is to report the 87Sr/86Sr ratios in rain-water, stream-water, soils and rocks in two Scottish catchments and to relate these data to mineral weathering in the soils as the first stage in a more detailed study being carried
